ALBERT BIRD, OF LYNN, MASSACHUSETTS.

LUNCH-BOX.

To all whom it may concern:

Be it known that I, ALBERT Brno, a subject of the King of Hungary,residing at Lynn, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Lunch-Boxes, ofwhich the following is a specification, reference being had therein tothe accompanying drawing.

This invention relates to collapsible lunch boxes, and the objects ofthe invention are to provide a lunch box that can be reduced in itsdimensions to form a small parcel that can be easily carried in thepocket of the coat, and to furnish a lunch box with simple and effectivemeans that will permit of it being easily and quickly collapsed orrestored to a set-up position.

Other objects of the invention are to provide a sanitary lunch box, andto accomplish the above results by a box that is simple and durable.

\Vith these and such other objects in view as may hereinafter appear,the invention consists of the novel construction, combination andarrangement of parts to be hereinafter specifically described and thenclaimed.

Reference will now be had to the drawings forming a part of thisspecification wherein there is illustrated a preferred embodiment of theinvention, but it is to be understood that the structural elementsthereof can be varied or changed without departing from the scope of theappended claim.

In the drawings :Figure 1 is a perspective View of the lunch box. Fig. 2is a longitudinal sectional View of the same. Fig. 3 is an end view ofthe box collapsed. Fig. 4i is a side elevation of the same. Fig. 5 is avertical sectional View of the collapsed box, and Fig. 6 is a plan ofthe box partly collapsed.

My improved lunch box is preferably constructed of metal and leather,the metal being in the form of skeleton frames pivotally connectedtogether and strap hinges for retaining the pivoted frames together,while the leather used is of a light and flexible character in orderthat it can be easily folded. The bottom of the box is formed by twoU-shaped metallic frames 1 having the side arms 2 thereof pivotallyconnected together, as at 3. Sultably secured to the frames 1 are thelower edges of side walls 4 and end walls 5. These walls are preferablymade of one piece of material having Specification of Letters Patent.

the ends thereof connected, as at 6. The lower edges of the walls arewrapped around the frames 1 and are sewed to the walls, as at 7 the samesewing retaining the bottom 8 between the side walls. The lower edges ofthe side walls are cut away, as at 9, to provide clearance for thepivoted ends of the side arms 2. The upper edges of the side walls 4 and5 are bent over two frames 10 similar to the frames 1, said frameshaving the arms 11 thereof pivotally connected, as at 12. The upperedges of the side walls are sewed, as at 13, similar to the lower edgesthereof, and the side walls 4 are cut away, as at 14:, to provideclearance for the pivoted ends of the arms 11. Pivotally connected tothe side arms 2 and 11, as at 15, are links 16 having their endsconnected, as at 17.

The lid or cover of the box is formed of two U-shaped wire frames 18having the ends thereof terminating at oppositely disposed cut awayportions 19 of a cover 20 mounted upon said frames, the cover having theedges thereof extending under the frames and sewed, as at 21. One of theframes 18 is connected to one of the end walls 5 by a strap hinge 22,said hinge being riveted to the wall 5, as at 23, and to the cover 20,as at 24;. The opposite end of the cover is provided with a pivoted link25 adapted to be held by a pivoted clasp 26, carried by the inner sideof the wall 5 and extending through an eyelet 27 provided therefor inthe wall 5. This clasp is of a conventional form such as used upon largeover-shoes.

With the lunch box empty and without removing the cover 20, the box canbe collapsed and folded somewhat similar to a pocket-book. The pivotedconnection 17 of the link 16 is broken to throw the links out ofalinement, and then the frames 10 can be lowered upon the frames 1 withthe links folded as shown in Fig. 6. The ends of the frames 1 and 10 canthen be swung upwardly, as shown in Fig. 5, thereby folding the box intoa comparatively small parcel.

Having now described my invention what I claim as new, is

A collapsible lunch box comprising a body portion and a cover, said bodyportion including an upper and a lower pair of U- shaped frames, theframes of each pair pivotally connected at their inner ends, flexibleside and end walls having their upper portions overlapping the upperpair of frames posing ends, means for pivotally connecting and securedtogether and having their lower the upper ends to the upper frames,means portions overlapping the lower pair of for pivotally connectingthe lower ends of frames and secured together, said side walls the linksto said lower frames, and a cover 15 at their top and bottom cut away toprohinged to the body portion.
